  • JVM1LE(CM1LE) Moulded Case Circuit Breaker

    JVM1LE(CM1LE) Moulded Case Circuit Breaker

    Application

    JVM1LE series moulded case circuit breaker with residual current production. Rated insulation voltage is 800V. It applies to circuit of AC 50Hz, rated working voltage 400V and rated working current up to 630V,for in frequent switch over and infrequent start of motor. With overload, Short circuit and under-voltage production, itcan protect circuits and power-supply equipment from damage, can also be used for production from damage andany potential fire hazard caused by long existing earth fault which can not be detected by over-current production.The value of residual current is selectable.

    Load isolation switch

    Product description

    Modular design structure, flexible and diverse combination, using glass fiber reinforced unsaturated polyester resin to make the shell, with high dielectric performance, protection ability and reliable operation safety.

    The operating mechanism is an accelerating mechanism with spring energy storage and instantaneous release, which instantaneously connects and breaks the double-breakpoint contact structure. It has nothing to do with the speed of the operating handle, which greatly improves the electrical and mechanical properties.

    A variety of structures and operation methods, there are windows for directly observing the on-off state of the contacts, operations inside and outside the cabinet, front and side operations, and back-to-board wiring.

  • JVM 5 (EZC) type case circuit breaker

    JVM 5 (EZC) type case circuit breaker

     

    Application

     

    JVM5MCCB is a simple and unlimited solution that can meet all low-voltage protection needs.

    The circuit breaker has a compact structure and reliable quality, which greatly improves the high segmentation capability. It can be seen from the design that the riveting material in the operating mechanism must be matched according to the actual product in the design; each part must not only have a precise calculation of the size, but also consider the mutual cooperation between them, in order to make the assembled whole Meet the calibration standards. It can be understood from the calibration analysis that the instantaneous action characteristics in the electromagnetic system are closely related to the operating mechanism. After the calibration parameter values are obtained through theoretical research, strict test verification is required to meet the product standards; the extension of the calibration electric heating system The time trip value also needs to be obtained based on the combination of the calculated value and the actual value.

  • Isolating switch

    Isolating switch

    The function of the fuse is to protect the current. The fuse is composed of a melt and a fuse tube, which are connected in series as a metal conductor in the circuit. When the current exceeds a certain value, the fuse will generate heat to melt the melt, thereby breaking the current and achieving the protection effect. Fuses are widely used in various electrical and electrical equipment due to their simple structure and convenient use.
